`nvm-mevr:Mrzrm nr WINDOW-seen SUPPORTI:

The vSchedule referred to in `Izlzles'e Lettes Patent and making part of the name.

To all whm'i, it may concern.

Be it known that I, ASA H. um, of rlitfwryv'ilit,

in the county of\Vyoming, in the Stat-e of Pennsylvania, have invented new and useful Improvements in -Apparatus for Raising nd LoweringWindow-Sash, and holding them in' any desired position in the frame; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,- inaking a part ofthis specication, in which-fl Figure 1 represents a vertical edge view of a double` sash, in section, with the apparatus attached.

Figure 2 shows a broken-off` section of flame, top sash, rail, and apparatus-front View.

Figure 3 shows a top view ofthe windlass, attached to the top rail of bottom sash.

Figure 4is zi. fr'ont sectional view` of the apparatus, showing the ratchet, pawl, and brake, in red lines.

The object of my invention is. to control the raising and lowering of hot-hbottom and .top window-sash,

Without the application and use of weights to'balance them, and to `easily regulate the opening either at the top or bottom, -or bot-h, without handling the sash.

.Myinvention consists in the windlass, as "constructed,

combined with 'a cord and single pulley, and applied to operate in the manner hereinafter described and set l forth.

To enable others to make, apply, and use'my invention, I will describe it more fully, referring to the drawings, and to the letters marked thereon.

To. the middle of the top rail A of the lower sash,- I attach the windlass B, supported in the frame b b, so as to veasily turn in either direction by the crank G, in front, the windlass B being provided with a ratchetwheel, D, and a hook-pawl, d, pivoted v`in 4its centre over the ratchet D, and provided with a rod, E, at the opposite end 'om the hook d, tolit the hookfrom ,the l teeth a f a, and, at the same time, operate'as a brake on the windlass, to prevent the weight of the sash from moving. too fast.

To theibarrel of the windlass'B is attached acord, F, which passes over the stationary pulley f, in the top of' the window-frame G,.and connects with the top sash H, so thatwhen both the sashes'are closed it' .is only necessary to lift the bottonisash, and the top sash will let down in the sameV proportion, the same as those which balance each other. And whenv the lower sash is to be, raised, it is only necessary to take hold' of the crank-handle I, and tiirn to the right and.

wind the sash up. And when the sash Avis to be let down, it is only necessary to take hold 'of the ring J,

on the rod E, and lift the pawl d from ythe teeth ofthe ratchet D, the other end acting as a. brake to ease th'e g sash down` f And-When it is desirable to let down the top sash only; the 4same operation of liftingthe paw] d3 from the ratchet wheel' D, by the rod E, is performed,

Thus, it will beseen that my improved apparatus for raising, lowering; andbalancing sash,iisboth sini ple, cheap, and eiicient. Y

.Having thus fully described my invention, and its practicaloperation, f

What I claim as new, and desire to secure by Let- Patent, 'is-' 4The direct' action of the Windlass B and cord F, on a singlecent-ral pulley j; whereby the misngand lowering of both the top and bottom sash are eii'ected, substantially in the manner hereinshown and set forth.
